DESCRIPTION

The KF00 series are very Low Drop regulators

available in SO-8 package and in a wide range of

output voltages.

The very Low Drop voltage (0.4V) and the very

low quiescent current make them particularly

suitable for Low Noise, Low Power applications

and specially in battery powered systems.

A Shutdown Logic Control function is available

(pin 5, TTL compatible). This means that when

the device is used as a local regulator, it is

possible to put a part of the board in standby,

decreasing the total power consumption. It

requires only a 2.2

allowing space and cost saving.
